“After I had Jayden, it was real easy for me to get back in shape,” Spears said during an interview with Women’s Health in 2014. “But five years later, I started noticing changes in my body. My hips are a little bit wider because I’ve had kids. So it was crucial for me to be continuous with my exercise. Consistency is key.”
